SPECIFICATION forming part of Letters Patent No. 757,918, dated April 19, 1904.

A Application filed August 18, 1903. Serial No. 169,932. (N model J To r/Z/ whom, it 'may concern:

Be it known that I, HARRY S. HANsTINn, a citizen of the United States of America, residing at `Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Vises, of which the following is a speciiicatiomreference beinghad therein to the accompanying drawings.l

This invention relates to certain new and useful improvements in vises, the primary object of the invention being to construct a vise in which the jaws are capable of being inclined to different positions or angles, whereby to I5 bring said jaws to any desired position, and, furthermore, to provide a vise in which one of the jaws is adjustable independently of the other jaw, whereby to position the jaws to conform to the particular shape of piece being 2O held.

A further object of the invention is to pro-- vide a vise of a simple and effective nature comparatively inexpensive to manufacture;

and the invention resides in the novel construction, combination, and arrangement of parts to be hereinafter more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings,

forming a part of this application, and wherein like numerals of reference indicate like parts throughout the several Views, in which- Figure 1 is a central vertically-longitudinal sectional view of my improved vise. Fig. 2

3 5 is a horizonal sectional view of the same.

Fig. 3 is a top plan view, the jaws being partly broken away. Fig. 4 is a cross-sectional view taken on line 4 4 of Fig. 1. Fig. 5 is a plan view of the bearing-nut for the outer jaw.

Fig. 6 is a detached detail perspective view of the adjusting-ring. Fig. 7 is a detached detail plan view of the conveXo bearing-nut.

Fig. 8 is a front view of the socket member or shell of the vise. Fig. 9 is a longitudinal sectional View of the same. Fig. 10 is a detached side elevation of the lock-arm for holding the jaws inthe adjf-isted position. Fig. 11

is a plan view of the same. Fig. 12 is an underneath plan view of the` bed-plate ofthe vise. Fig. 13 is a horizontal sectional view of the same. Fig. 14 is a detached detail perspective view of the inner jaw. Fig. 15 is a like view of the barrel on which the jaws are mounted. Fig. 16 is a similar view of the outer jaw.

To put my invention into practice, I provide a barrel 1, which receives the operatingscrew 2 therethrough and is slotted, as at 3, from its inner end to a point near its outer end in order to permit its passage through the segmental openings 3', provided therefor in the convexo lock-nut 4. The providing of the lock-nut 4'with the segmental openings 3 forms a spider 4', having the threaded opening 5 to receive the operating-screw 2. This screw has a stem 5 extending through the shank 6 of the barrel and having connected to its outer end, as by a pin 7 or other approved means of connection, a T 8, which receives the operating lever or handle 9 of the usual form of construction. The segmental cutaway portions 3 besides receiving the barrel 1 also receive the sleeve 11, which carries the inner jaw 12, this sleeve surrounding the barrel 1 and being held by means of a jamnut 14, threaded onto its inner end. In order to pass the sleeve through the nut 4, it `will of course be evident that the sleeve must be provided with a slot 11', and in casting the parts it is the practice to cast the jaw 12 and the sleeve integral, providing the core, which leaves a portion of the sleeve unslotted at its inner end in order that the thread may be readily cut on said nut, and after this thread is cut the portions are chiseled out to extend the slot through to the inner end ot' the sleeve. The jaw 12 is provided on its rear face with an annular flange 15, which engages the concave lip or extension 16, carried by the body or bed plate 17, and also engages the conveXo faces 20, carried by the socket member or shell 21, the substantially elliptical-shaped opening 22 of which receives the' sleeve 11 and barrel 1. The shell or socket member is made integral with the bench-plate 19, which is suitably bolted or otherwise secured to the bench or other support. (Not shown.) This bench-plate is provided in its forward edge with a cut-away portion tol receive the plate 17 and is provided on its underneath face with a rib 18, having a beveled forward face 18 to receive the beveled edge 16l of the plate 17. The plate 17 and its curved extension 16 is merely a filling-in piece and is only intended to be used in connection with the vise when the latter is in its lowermost position-that is, the position shown in Fig. 1. The purpose of plate 17 is to prevent filings, shavings, or small tools from falling through the cavity which it fills, and it is removed when the vise is to be raised above the position shown in Fig. 1. The socket member 21, as stated, is integral with the bench-plate 19 and at its lower end is provided with a curved slot 23, through which is passed the curved guide-armA 24;, which also acts as one of the instrumentalities for holding the vise in the adjusted position. This curved guide-arm is adapted to be moved within thefcurved slot and is securely held in any desired position by means of a set-screw 26 or other desirable securing means, the arm having a head 25, which acts as a stop to limit the movement of the arm in one direction.. This stop is adapted to engage in the opening 28 provided therefor in the socket or shell 21 and shaped correspondingly to the shape of the head or stop 25.

The purpose of curved arm 24 is to assist in holding the vise when it is adjusted at an angle to the top of the bench, the arm being held at its upper end by thefiange 15 of the inner-jaw 12 and the curved arm being held when the vise is' raised by the set-screw 26.

On the shank 6 of the barrel is an annular beveled shoulder 29, and surrounding this shoulder is an independently-adjustable outer jaw 30, provided on its outer face with a concave seat 31, its inner face being provided with a seat 31, surrounding the opening and through which the shank 6 extends and conforming to the seat or shoulder 29 of said shank. A nut 32 is loosely mounted on the shank 6, the said nut having an ellipticalshaped opening 32 to receive the shank and having a conveXo face 33 to engage with the concave seat 31 of the jaw- 20, this nut being held on shank 6 by means of the jam-nut 34.

threaded onto the outer end of the shank 6 of the barrel. The nut 32 is recessed in its outer face, as at 34', and the walls of this recess have two oppositely-disposed straightline faces 35, that are engaged by the two oppositely-disposed straight-line faces 36, provided on the adjusting-ring 37, which is seated in the. recess 34: in the outer face of nut 32. This adjusting-ring has a substanto the ring is an ad justing-screw 39, the neck 10 of which operates in the wall of nut 32. It will be observed that when this screw 39 is turned the adjusting-ring 37 will be moved within the recess 34', moving the adjusting-ring laterally within the recess and adjusting the position of nut 32, according to the direction in which the screw 39 is turned. After the jaw l30 has been adjusted to the desired angle it is held by means of a setscrew 4:1, which impinges against seat 29 of the shank 6, or other approved locking means may be employed. The nut 32, it is to be noted, is loosely mounted, thereby permitting suflicient clearance between this nut and the shank of the barrel to permit of the rocking movement of the nut on the shank, and it is to be noted that when the adjustingring is actuated so as to incline the nut to the vertical-that is, for instance, force the upper half of the nut toward the jaw 30 and lower half of the nut away from the jaw 30, or vice versathat the jaw can then be inclined accordingly with respect to the jaw 12, and after adjusted to the desired position the jaw 30 is securely held by tightening setscrew 41.

The loosening of set-screw 26 enables both of the jaws to swing, the vise swinging in its bearings, so as to bring parts to the desired position, either at an incline to the vertical or at an incline to the horizontal line, or both, as may be desired. The provision of means which permits the independent adjustment of Y the outer jaw enables me to adjust this jaw whereby to accommodate tapered or other IOO special shapes which it may be desired to hold.

It will be obvious that various slight changes may be made in the details of construction without departing from the general spirit of my invention.

Having .fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
